血粉酶解的发酵工艺条件优化研究
发布时间：2018-09-01 11:31
【摘要】：目前蛋白资源匮乏现象日益严重,开发新的蛋白资源和合理利用现有的蛋白资源成为畜牧业亟待解决的问题。血粉资源丰富,且蛋白含量高,但是血粉适口性差,氨基酸不平衡,因此大部分被浪费了。合理利用血粉不仅可以缓解蛋白资源短缺的现状,还可以减少环境污染。酶解血粉的发酵工艺优化是通过培养条件和培养基选择提高菌株产酶能力,复合菌株产蛋白酶类型和种类互相补充,使蛋白酶系更为齐全,使血粉蛋白质的酶解更充分,消化率率更高,且改善了血粉的适口性,增加了血粉的饲用价值。该血粉的研发既有效缓解了蛋白资源短缺的现状,又有效利用了血粉资源,具有较大的现实意义。
[Abstract]:At present, the shortage of protein resources is becoming more and more serious, so the development of new protein resources and the rational utilization of existing protein resources have become the urgent problems to be solved in animal husbandry. Blood meal is rich in resources and high in protein content, but its palatability is poor and amino acid is not balanced, so most of them are wasted. Reasonable utilization of blood powder can not only alleviate the shortage of protein resources, but also reduce environmental pollution. The optimization of fermentation technology of blood powder by enzymatic hydrolysis is to improve the enzyme production ability of the strain through the selection of culture conditions and culture medium, and supplement each other with the types and types of protease produced by the compound strain, so that the protease system is more complete and the enzymatic hydrolysis of blood meal protein is more adequate. The digestibility was higher and the palatability of blood meal was improved, and the feeding value of blood meal was increased. The research and development of the blood powder not only alleviated the current situation of protein resource shortage, but also utilized the blood meal resource effectively, which is of great practical significance.
